/********************************************************************** * *  geo_tiffp.h - Private interface for TIFF tag parsing. * *   Written by: Niles D. Ritter * *   This interface file encapsulates the interface to external TIFF *   file-io routines and definitions. The current configuration *   assumes that the "libtiff" module is used, but if you have your *   own TIFF reader, you may replace the definitions with your own *   here, and replace the implementations in geo_tiffp.c. No other *   modules have any explicit dependence on external TIFF modules. * *  Revision History; * *    20 June, 1995      Niles D. Ritter         New *    6 July,  1995      Niles D.
